Criptext for Gmail

Criptext supercharges your Gmail with security and control. Send encrypted emails from with just checking a box. Track who, when and where your emails have been opened. Sent an email to the wrong person? Recall sent emails at anytime – even after they’ve been read. Add an expiration timer on your email if you’re sending time-sensitive material.
Finally, easily send secure attachments to anyone. Add up to 100mb per attachment seamlessly. Best of all: recipients don’t need to have Criptext to read your secure emails. They can read them right from their inbox!
